Adelaide and Port Adelaide are still in South Australia after this afternoon’s scheduled flights to Queensland were cancelled amid the COVID-19 drama.
It means the Showdown could be moved forward from Round 21 to this weekend.
At this stage, however, Port Adelaide are scheduled to face Collingwood at Adelaide Oval on Friday, while the Crows are fixtured to face the Hawks on Saturday at the same venue.
The AFL is facing several massive decisions regarding fixturing.
The league is currently in a phone hook-up with the Crows and Power in an attempt to find clarity on what the coming days will look like.
Essendon, Brisbane, Gold Coast, GWS and Sydney are all currently based in Queensland.
South Australia will go into a seven-day lockdown from 6pm tonight after the state recorded two new cases of coronavirus in the community.
Premier Steven Marshall confirmed the outbreak was the highly transmissible Delta strain.
“The reality is we are dealing with a different variant to last year’s Parafield cluster,” Marshall said.
“This is a highly infectious strain and that is why we are taking these extreme precautions.”
